Downloads through the Brave browser are not appearing in the Recent Items List of Outlook (when attempting to attach a file). This lack of sharing creates a lot of additional work browsing for files to attach. I’ve had to return to Chrome when working because this limitation severely slows down my workflow, and breaks and incredibly useful Outlook feature.
I do realize that sharing of information with other apps is sort of against the Brave ethos. So it would probably need to be a feature that can be toggled on/off.
